I have a couple of favourite genres but i never had any of these problems.
Does op only play third person action rpg? Why not playing an fps, a tps, an isometric game, a platform, and rpg, anything else?
It always sound absurd to me playing a game and being stuck because you don't like anything else after that, i can understand if someone only play one single genre, but who the fuck does that in here?
Also, i'm pretty slow when i play souls games, my shortest run is probably something like 50 hours at minimum, usually is around 80-100 hours so after all that time on a single game, i surely don't want another one right after...
Maybe it's because i play both AAA, AA and indies so i have way more choice, but yeah, i don't know dude...
I think it depends on the person, some people really think that souls games are the pinnacle of gaming, perfect games in all aspects, better than sliced fleshlight etc., For me they are just another great saga with big plus and big downsides, i can live without playing souls everyday.
